DETAILED DESCRIPTION

[0040] It should be noted that the principles of the present application are exemplified by being implemented in a suitable operating environment. The following description is based on the exemplified embodiments of the present application, which should not be regarded as limiting other embodiments of the present application not described in detail.

[0041] In the following description of the present application, "some embodiments" are described, which describe a subset of all possible embodiments, but it can be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict.

[0042] In the following description of the present application, the terms "first, second, third" are only to distinguish similar objects, and do not represent the specific order of the objects. It can be understood that "first, second, third" can be interchanged in specific order or sequence as allowed, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0044] Please refer to Figs. 1-2 The cleaning device provided by the present application has the following structure:

[0045] The cleaning device comprises a cleaning assembly 1 and a connecting component 2 detachably connected with the cleaning assembly 1. During use, the connecting component 2 is connected with an external device, for example, a mechanical arm. The mechanical arm is connected with the connecting component 2, and then the mechanical arm drives the cleaning assembly 1 to move, so that the cleaning assembly 1 approaches the working surface to be cleaned and performs cleaning work on the working surface.

[0046] Moreover, through the detachable structure between the cleaning assembly 1 and the connecting component 2, different connecting components 2 can be replaced, so that the connecting component 2 can be better connected with different types of external devices, thereby improving the adaptability of the cleaning device.

[0047] Further, the connecting component 2 comprises a connecting piece 21 and a fixing piece 22 matched with the connecting piece 21. One end of the connecting piece 21 is detachably connected with the cleaning assembly 1, and the other end is connected with the external device and fixed with the fixing piece 22.

[0048] Specifically, in some embodiments, the connecting piece 21 comprises a connecting cylinder, which is in a cylindrical shape. An outer thread is arranged on one end of the connecting cylinder. A threaded hole is arranged on the side of the cleaning assembly 1 close to the connecting cylinder. The connecting piece 21 is threadedly connected with the cleaning assembly 1 through the threaded hole. The fixing piece 22 comprises a fixing pin. The connecting cylinder is provided with pin holes in the direction perpendicular to the axis of the connecting cylinder. The pin holes are two and symmetrically arranged through the connecting cylinder. The fixing pin is inserted into the pin holes.

[0049] When the cleaning assembly 1 needs to be moved, the user sets the external device on the connecting cylinder, aligns the fixing holes on the external device with the pin holes, and then inserts the fixing pin through the fixing holes and the pin holes, so as to fix the external device with the connecting cylinder. The fixing through the insertion of the fixing pin is also relatively convenient and fast.

[0050] Moreover, in order to adapt to different sizes or different shapes of the connecting part between the external device and the connecting piece 21, the connecting piece 21 is detachably connected with the cleaning assembly 1, so that different types of connecting pieces 21 can be conveniently replaced, thereby improving the adaptability of the cleaning device when connected with the external device.

[0051] Therefore, in some embodiments, the connecting piece 21 can also be other shapes, for example, can be cylindrical, can also be prismatic, or other shapes, and the embodiments are not limited thereto. The connecting manner of the connecting piece 21 and the cleaning assembly 1 can also be that a threaded column is fixed on the side of the connecting piece 21 close to the cleaning assembly 1, and the threaded column is threadedly connected in a threaded hole to realize the detachable connection of the connecting piece 21 and the cleaning assembly 1.

[0052] Meanwhile, in order to improve the stability of the fixing pin, one end of the fixing pin is fixed with a disc with a diameter larger than that of the fixing hole, and the other end is provided with a through hole for inserting the fixing strip, the through hole is provided along the length direction perpendicular to the fixing pin, and after the fixing pin is inserted into the fixing hole and the pin hole, the disc can limit one end of the fixing pin, and then when the end of the fixing pin away from the disc passes through the other pin hole and extends to the outside of the external device, the fixing strip can be inserted into the through hole to limit the fixing pin, thereby preventing the fixing pin from falling off, and the fixing strip can be a wire.

[0053] The cleaning assembly 1 comprises the cleaning head 3 and the swing frame assembly 4, one end of the swing frame assembly 4 is detachably connected with the connecting piece 21, and the other end is rotationally connected with the cleaning head 3. In the embodiments of the application, the external device is taken as an example of a mechanical hand, and through the rotational connection of the swing frame assembly 4 and the cleaning head 3, when the mechanical hand is connected with the swing frame assembly 4 through the connecting piece 21, the angle between the cleaning head 3 and the swing frame assembly 4 can be adjusted when the cleaning head 3 is close to the working surface to be cleaned for work, so that the mechanical hand moving the cleaning assembly 1 during the cleaning process can adapt to different angle working surfaces, thereby improving the adaptability of the cleaning device.

[0054] In one embodiment, the swing frame assembly 4 comprises a first swing frame 41 and a second swing frame 42, the first swing frame 41 is detachably connected with the connecting piece 21, and the second swing frame 42 is rotationally connected with the first swing frame 41 and the cleaning head 3 respectively, and the rotational axis of the cleaning head 3 and the rotational axis of the first swing frame 41 form an angle. In this way, when the mechanical hand controls the cleaning head 3 to move, since the second swing frame 42 is rotationally connected with the first swing frame 41 and the cleaning head 3 respectively, the angle of the first swing frame 41 can be adjusted around its own rotational axis, and in this process, the cleaning head 3 adjusts the angle around its own rotational axis, so that the cleaning head 3 can adjust the angle of the cleaning working surface in two directions, so that the cleaning device can better adapt to different angle working surfaces.

[0055] Specifically, in one embodiment, the first swing frame 41 is in the shape of a "n" and the open end of the first swing frame 41 faces the cleaning head 3. The first swing frame 41 includes two parallel connecting plates 413 and a cross plate 412 connected to the same end of the two connecting plates 413. The first swing frame 41 can be integrally formed or the connecting plates 413 and the cross plate 412 can be fixed by welding. A threaded hole is formed in the center of the cross plate 412 and the threaded hole is parallel to the length direction of the two connecting plates 413. The connecting member 21 is screwed into the threaded hole.

[0056] The second swing frame 42 is in the shape of a frame and the two parallel side frames of the second swing frame 42 are respectively provided with a first shaft hole. The two first shaft holes of the second swing frame 42 are symmetrically arranged. Meanwhile, the two connecting plates 413 of the first swing frame 41 are also provided with a first shaft hole at the end away from the cross plate 412. The first shaft hole of the connecting plate 413 is parallel to the length direction of the cross plate 412. During installation, the first shaft holes of the two connecting plates 413 and the first shaft holes of the second swing frame 42 are aligned, and then the first pin shaft 411 is inserted into the first shaft holes. The first pin shaft 411 respectively passes through the first shaft holes of the connecting plate 413 and the second swing frame 42 on the same side, so that the connecting plate 413 can rotate around the two first pin shafts 411, and the first swing frame 41 can rotate around the two first pin shafts 411.

[0057] It should be understood that the first swing frame 41 rotates around the first pin shaft 411, and the first pin shaft 411 can also limit the first swing frame 41. The shape and limiting of the first pin shaft 411 can refer to the fixed pin. In this way, the first pin shaft 411 can be extracted or inserted, the overall disassembly or installation between the first swing frame 41 and the second swing frame 42 can be realized, and the modular installation method is more convenient.

[0058] Further, the surface of the end of the first pin shaft 411 away from the disc thereof can be provided with external threads. When the first pin shaft 411 is inserted into the first shaft hole and extends to the outside, the first pin shaft 411 can be fixed by screwing a nut on the first pin shaft 411. There is at least one nut, and it should be understood that the diameter of the disc of the first pin shaft 411 and the nut is greater than the diameter of the first shaft hole. When the nut is fixed, a wire or other fixing strip can be inserted into the through hole of the first pin shaft 411 for further fixation, which can prevent the nut from falling off.

[0059] Meanwhile, two side frames of the second swing frame 42, which are perpendicular to the side frame with the first shaft hole, are respectively provided with a second shaft hole, and the two second shaft holes are symmetrically arranged, and the axis of the first shaft hole is perpendicular to the axis of the second shaft hole, and meanwhile, the second swing frame 42 can be integrally formed or fixed by welding, and the embodiment does not limit this.

[0060] The side frame of the second swing frame 42 with the first shaft hole is the first side frame 422, and the side frame with the second shaft hole is the second side frame 423, and the first side frame 422 is fixed perpendicularly to the adjacent second side frame 423. Meanwhile, at least one support seat 37 is fixed to the side of the cleaning head 3 close to the second swing frame 42.

[0061] The two support seats 37 are fixed to the upper surface of the cleaning head 3, and the fixing mode can be welding or bolt fixing, and the upper surface of the cleaning head 3 is the side close to the second swing frame 42, and the support seats 37 are symmetrically arranged on both sides of the central position of the upper surface of the cleaning head 3, and the support seat 37 is plate-shaped, and the side surface of one end of the support seat 37 close to the second swing frame 42 is provided with a second shaft hole, and the opening direction of the second shaft hole of the support seat 37 is the same as and corresponds to the opening direction of the second shaft hole of the second side frame 423.

[0062] During installation, the second shaft hole of the support seat 37 is aligned with the second shaft hole of the second side frame 423, and then the second pin shaft 421 matched with the second shaft hole is inserted into the second shaft hole, so that the second swing frame 42 or the cleaning head 3 can rotate around the second pin shaft 421, wherein the second pin shaft 421 is completely the same as the first pin shaft 411, and of course, the two can also be different in size but the same in shape and structure. Through the detachable connection of the second swing frame 42 and the cleaning head 3 by the second pin shaft 421, the modular disassembly or connection can also be achieved, and the operation is more convenient.

[0063] And since the axis directions of the first pin shaft 411 and the second pin shaft 421 are both in the horizontal direction and perpendicular to each other, if the rotation of the first swing frame 41 around the first pin shaft 411 is forward and backward rotation, then the rotation of the second swing frame 42 around the second pin shaft 421 is left and right rotation, and if the rotation of the first swing frame 41 around the first pin shaft 411 is left and right rotation, then the rotation of the second swing frame 42 around the second pin shaft 421 is forward and backward rotation, so through this connection mode, the robot can adjust the cleaning device from two directions when the robot controls the cleaning device to clean the working surface, so that the cleaning head 3 can better clean the working surface, and thus can better adapt to different angle working surfaces.

[0064] Further, in one embodiment, in order to prevent the first swing frame 41 and the second swing frame 42 from being connected with the robot arm and to prevent the cleaning head 3 from being stable during operation, the swing frame assembly 4 needs to have a certain stability, that is, the swing frame assembly 4 can maintain a certain angle without external interference, so the swing frame assembly 4 further comprises an elastic connecting piece 4321.

[0065] One end of the elastic connecting piece 4321 is connected with the cleaning head 3, and the other end is connected with the first swing frame 41 and / or the second swing frame 42, that is, the elastic connecting piece 4321 can be connected with the cleaning head 3 at one end and directly connected with the first swing frame 41 at the other end, so as to realize the stability of the angle of the swing frame assembly 4 through the elastic connecting piece 4321, or the other end is directly connected with the second swing frame 42, so as to realize the stability of the angle of the swing frame assembly 4 through the elastic connecting piece 4321, or the other end is connected with the first swing frame 41 and the second swing frame 42, so as to realize the stability of the angle of the swing frame assembly 4 through the elastic connecting piece 4321.

[0066] Further, the present embodiment is described in the mode that the elastic connecting piece 4321 is connected with the first swing frame 41 and the second swing frame 42. The elastic connecting piece 4321 comprises at least two first spring pieces 431 and at least two second spring pieces 432. The first swing frame 41 is fixed with at least two symmetrically arranged first connecting pieces 414, and the two first connecting pieces 414 are symmetrically arranged on the two side walls of the horizontal plate 412, and the first connecting piece 414 is located on one side of the first swing frame 41 in the direction of rotation. Specifically, it is fixed on the side wall of the horizontal plate 412 without the connecting plate 413.

[0067] In the present embodiment, the first spring piece 431 is four, and the two side walls of the horizontal plate 412 are each fixed with two connecting pieces, which are located near the two ends of the connecting plate 413, that is, four connecting pieces are fixed on one horizontal plate 412, and each side near the two ends of the horizontal plate 412 is fixed with a pair of symmetric connecting pieces. Correspondingly, the outer side wall of the second frame 423 is also fixed with two second connecting pieces 424, and the two second connecting pieces 424 are respectively located at the two ends of the second frame 423. The second connecting piece 424 is provided with at least two second connecting holes in the length direction of the second frame 423, and the first connecting piece 414 is provided with at least one first connecting hole in the length direction of the horizontal plate 412.

[0068] During use, hooks are fixed at both ends of the first spring member 431 and the second spring member 432, the hook at one end of the first spring member 431 is hung in the first connecting hole, and the hook at the other end is hung in the second connecting hole on the same side, at this time, the first swing frame 41 is symmetric in the left-right direction and the front-rear direction with four first spring members 431 arranged thereon. In this embodiment, the first spring member 431 and the second spring member 432 are both tension springs, and the mutual symmetric tension of the tension springs can fix the angle of the first swing frame 41, so that the first swing frame 41 is always in a state that the connecting plate 413 is perpendicular to the first frame 422 without being affected by external force.

[0069] At the same time, the upper surface of the cleaning head 3 is fixed with a third connecting piece 313, the third connecting piece 313 is also arranged in pairs and symmetrically, and the third connecting piece 313 can be located on the side close to the first pin shaft 411 or the side close to the second pin shaft 421 on the upper surface of the cleaning head 3, and in this embodiment, the side close to the second pin shaft 421 is taken as an example. At least one third connecting hole is formed in the third connecting piece 313, one end of the hook of the second spring member 432 on the same side is hung in the second connecting hole, and the other end is hung in the third connecting hole, and the two second spring members 432 on the same side are symmetrically arranged, and a pair of spring members on different sides are also symmetrically arranged.

[0070] The third connecting piece 313 is located on the center line of the connecting line of the two second connecting pieces 424 on the same side, so when the second spring member 432 on the same side is hung in the third connecting hole at the same time, the second swing frame 42 on both sides is subjected to the same tension of the second spring member 432, so that the second swing frame 42 is always in a state that the connecting plate 413 is parallel to the upper surface of the cleaning head 3 without being affected by external force.

[0071] Therefore, under the influence of the tension of the first spring member 431 and the second spring member 432, the connecting member 21 is always in a state that it is perpendicular to the upper surface of the cleaning head 3, at the same time, even if the cleaning device is tilted, because the tension of the first spring member 431 and the second spring member 432 is sufficient, and under the influence of the gravity of the first swing frame 41 and the second swing frame 42, it is still insufficient to cause obvious deformation of the first spring member 431 and the second spring member 432, so at this time, the connecting member 21 is still in a state that it is perpendicular to the upper surface of the cleaning head 3, which is convenient for the connection between the mechanical hand and the connecting member 21.

[0072] When the connection is completed and the cleaning device is operated by the manipulator, the cleaning head 3 is in contact with the working surface, and the gravity of the cleaning head 3 is sufficient to cause the first spring member 431 and the second spring member 432 to deform obviously. In addition, the external force applied by the manipulator can further cause the first spring member 431 and the second spring member 432 to deform, so the angle between the swing frame assembly 4 and the cleaning head 3 can still be adjusted to facilitate the cleaning operation. Since the first spring member 431 and the second spring member 432 are located on the same side, the first spring member 431 and the second spring member 432 can fix the angle of the swing frame assembly 4 while reducing the resistance of the angle adjustment between the second swing frame 42 and the cleaning head 3, thereby facilitating the angle adjustment.

[0073] Further, in some embodiments, the cleaning head 3 includes a cleaning cover 31, a rotating body assembly 32, and at least one nozzle 33. Specifically, the opening side of the cleaning cover 31 is located on the side of the cleaning cover 31 away from the swing frame assembly 4, that is, the opening side of the cleaning cover 31 is the side close to the working surface to be cleaned and is adapted to the working surface to be cleaned. The rotating body assembly 32 is hollow and rotationally connected with the cleaning cover 31, and one end is located inside the cleaning cover 31 and the other end is located outside the cleaning cover 31. The nozzle 33 is located inside the cleaning cover 31 and connected with the rotating body assembly 32. When the water source is connected with the rotating body assembly 32 outside the cleaning cover 31, the water flow can enter the nozzle 33 through the rotating body assembly 32 and be sprayed from the nozzle 33 to clean the working surface.

[0074] Specifically, in the present embodiment, the cleaning cover 31 includes a shell 311 and a cover plate 312. The shell 311 is in the shape of a flat cylinder, and the diameter of the cover plate 312 is the same as the outer diameter of the shell 311. The cover plate 312 is detachably connected with the shell 311. The connection mode can be fixed by bolts or fixed by buckles, which is not limited in the present embodiment. The support seat 37 and the third connecting plate 313 are both arranged on the cover plate 312.

[0075] The rotating body assembly 32 includes a connecting pipe 321 and a tool holder 322 connected with the connecting pipe 321. The connecting pipe 321 is fixedly or rotationally connected with the cover plate 312, and one end of the connecting pipe 321 is located inside the cleaning cover 31 and the other end is located outside the cleaning cover 31. The tool holder 322 is rotationally connected with the connecting pipe 321. The nozzle 33 is arranged on the tool holder 322 and located on the side of the tool holder 322 away from the cover plate 312.

[0076] Specifically, a through hole is formed at the center position of the cover plate 312. When the connecting pipe 321 is fixedly connected with the cover plate 312, the connecting pipe 321 is inserted into the through hole and can be fixed by friction, can be fixed by welding, can be fixed by sealing glue, and so on. Of course, the connecting pipe 321 can also be fixed by a nut that is screwed on the connecting pipe 321 on both sides of the cover plate 312, and the connecting pipe 321 is limited by the nut. The present embodiment does not limit this.

[0077] When the connecting pipe 321 is rotationally connected with the cover plate 312, a bearing can be fixed in the through hole, and the connecting pipe 321 is fixed in the inner hole of the bearing to realize the rotation between the connecting pipe 321 and the cover plate 312. The tool holder 322 is rotationally connected with the connecting pipe 321 support. Similarly, a circular hole can be formed in the tool holder 322, a bearing is fixed in the circular hole, and one end of the connecting pipe 321 located in the cleaning cover 31 is inserted into the inner hole of the bearing. It should be understood that the outer diameter of the connecting pipe 321 is equal to or slightly larger than the inner diameter of the bearing, so that the connecting pipe 321 and the bearing can be fixed. Similarly, the outer diameter of the bearing is equal to or slightly larger than the diameter of the through hole and the circular hole.

[0078] The tool holder 322 is in a strip shape, at least one water flow channel is formed in the tool holder 322 along the length direction of the tool holder 322, the circular hole is connected with the water flow channel, the circular hole is located at the center position of the tool holder 322, a plurality of mounting holes connected with the water flow channel are formed on the side of the tool holder 322 away from the circular hole, and the nozzles 33 are mounted in the mounting holes and are inclined. The inclination direction of the nozzles 33 is opposite to the rotation direction of the tool holder 322. The inclination directions of the nozzles 33 located on both sides of the circular hole are opposite. Therefore, after the water flow passes through the connecting pipe 321, enters the water flow channel through the circular hole, and then enters the nozzles 33 through the mounting holes and is sprayed out, the tool holder 322 is pushed to rotate around the connecting pipe 321 under the impact of the water flow, and the rotating cleaning effect on the working surface is realized. It should be understood that the water flow channel is connected with the outside only through the mounting holes and the circular hole.

[0079] In another embodiment, the connecting pipe 321 is rotationally connected with the cover plate 312, and the tool holder 322 is fixedly connected with the connecting pipe 321. The difference from the above embodiment is that the tool holder 322 and the connecting pipe 321 do not need to be connected by a bearing, but only need to be fixed in the circular hole. The fixing mode can be screw connection, for example, an internal thread is formed in the circular hole, and an external thread that matches the internal thread is arranged on the outer side of one end of the connecting pipe 321 close to the tool holder 322, so that the connecting pipe 321 and the tool holder 322 are fixed by screw connection. Of course, the tool holder 322 and the connecting pipe 321 can also be directly fixed by welding.

[0080] When the connecting pipe 321 is rotationally connected with the cover plate 312, in order to prevent the water pipe from being wound when the connecting pipe 321 is connected with the water source, the end of the connecting pipe 321 located outside the cleaning cover 31 is coaxially rotationally connected with a connecting head 3211, which is connected with the external water source, so that the connecting pipe 321 can rotate while preventing the water pipe connected with the connecting pipe 321 from being wound. In this process, the knife holder 322 is pushed to rotate due to the water flow impact force, and further pushes the connecting pipe 321 to rotate, achieving the rotating cleaning effect on the work surface.

[0081] In some embodiments, the cleaning head 3 further comprises a cleaning sealing assembly 34 located at the opening side of the cleaning cover 31 and arranged along the circumference of the cleaning cover 31, for sealing the cleaning cover 31 and the work surface to be cleaned. Specifically, the cleaning sealing assembly 34 comprises a brush fixed along the circumference of the shell 311 away from the cover plate 312, and a flexible sealing rubber ring located outside the brush. When the cleaning head approaches the work surface, the brush can contact the work surface to clean the work surface during the movement of the cleaning head, and the sealing rubber ring can contact the work surface. Since the sealing rubber ring is flexible, for example, made of rubber, it can better contact the work surface during contact, and can seal the water entering the cleaning cover 31 to some extent, preventing the sewage from flowing randomly.

[0082] The surface of the shell 311 is fixed with a recovery pipeline 35 communicating with the inside of the cleaning cover 31. One end of the recovery pipeline 35 is located inside the cleaning cover 31, and the other end is located outside the cleaning cover 31, for communicating with the waste water recovery pipeline 35. Thus, when there is waste water in the cleaning cover 31, the waste water can be recovered through the recovery pipeline 35, which can reduce water resource waste and prevent sewage pollution as much as possible.

[0083] In some embodiments, in order to support the cleaning head 3, the cleaning head 3 further comprises a rolling support assembly 36, one end of which is connected with the cleaning cover 31, and the other end is provided with a rolling piece 362 abutting against the work surface to be cleaned, for supporting the cleaning head 3 to move on the work surface to be cleaned.

[0084] Specifically, the rolling support assembly 36 is at least one, and four in the embodiment, the rolling support assembly 36 includes a fixed plate 361 fixed to the cover plate 312, the fixed plate 361 can be fixed to the cover plate 312 by bolts, one end of the fixed plate 361 is fixed to the cover plate 312, the other end extends out of the cover plate 312 and is fixed with a rolling part 362, the rolling part 362 can be a universal wheel, and the fixed plate 361 can also be fixed to the cover plate 312 by bolts. When the brush of the cleaning head 3 and the sealing rubber ring are in abutment with the working surface, the universal wheel is also in abutment with the working surface, which can support the cleaning head 3, and the universal wheel can facilitate the movement of the cleaning head 3, thereby reducing the wear during movement.

[0085] As can be seen from the above, the present embodiment provides a cleaning device, which comprises a cleaning assembly 1 for cleaning a working surface to be cleaned; and a connecting component 2 detachably connected with the cleaning assembly 1, the connecting component 2 comprises a connecting piece 21 and a fixing piece 22 adapted to the connecting piece 21, one end of the connecting piece 21 is detachably connected with the cleaning assembly 1, the other end of the connecting piece 21 is used for connecting an external device, and the fixing piece 22 is used for fixing the connecting piece 21 and the external device. The mutual cooperation of the connecting piece 21 and the fixing piece 22 can reduce the complexity of connecting the mechanical equipment and the cleaning device, and the detachable connection of the connecting component 2 can improve the adaptability of the cleaning device and make the operation more convenient.
